PURPOSE:To obtain the titled fibers without requiring hot water, steam treatment, etc., by blending a polyester, e.g. polyethylene terephthalate based polyester, with a liquid crystalline polyester in a specific proportion and melt spinning the resultant blend. CONSTITUTION:(B) A liquid crystalline polyester, a polyester obtained by adding 20-80mol% compound expressed by the formula (R is 1-10C alkyl) to a polyester consisting of ethylene terephthalate units as main repeating units and blending both while heating is blended in (A) a polyester consisting of ethylene terephthalate as main repeating units at a ratio expressed by the formula 10<B/AX100<=40%. The resultant blend is then melt spun to afford the aimed fibers.
